Sarcoidosis is a multisystem inflammatory disease of unknown etiology. The lungs
and the lymphoid system are the most commonly involved organs. Extrapulmonary
involvement is reported in 30% of patients, and the abdomen is the most common
extrapulmonary site with a frequency of 50%-70%. Although intra-abdominal
sarcoidosis is usually asymptomatic, its presence may affect the prognosis and
treatment options. The lesions are less characteristic and may mimick neoplastic
or infectious diseases such as lymphoma, diffuse metastasis, and granulomatous
inflammation. The liver and spleen are the most common abdominal sites of
involvement. Sarcoidosis of the gastrointestinal system, pancreas, and kidneys
are extremely rare. Adenopathy which is most commonly found in the porta hepatis,
exudative ascites, and multiple granulomatous nodules studding the peritoneum are
the reported manifestations of abdominal sarcoidosis. Since abdominal sarcoidosis
is less common and long-standing, unrecognized disease can result in significant
morbidity and mortality. Imaging contributes to diagnosis and management of
intra-abdominal sarcoidosis. In this report we reviewed the cross-sectional
imaging findings of hepatobiliary, gastrointestinal, and genitourinary
sarcoidosis.
